Mumbai's Junior KG admission window for 2026-27 at schools like Bombay Scottish opened November 10, 2025 and closed December 15, 2025 — nearly three months before the citywide RTE quota window even opens. If you're starting your search in 2026 for the 2026-27 year, some of the city's most competitive private-school forms have likely already closed. That timing gap is the single biggest thing this guide wants you to walk away with.

Fee figures vary by campus, grade, and year and change annually — rather than repeat old numbers here, we recommend confirming current fees directly with each school's admissions office before shortlisting.

The Admission Calendar Reality for 2026-27

Two separate timelines run in parallel in Mumbai, and confusing them is the most common mistake we see parents make.

Private-school direct admissions (Nursery through Class 1, and lateral entry for older grades) are set independently by each school. As an example, Bombay Scottish's own admission notice for Junior KG 2026-27 shows form download and submission both running November 10 to December 15, 2025 — over two months before the calendar year even turned. Most reputed CBSE, ICSE, and IB schools in the city follow a similar September-to-December window for notifications and form collection, with interactions and offers continuing into February or March.

RTE 25% quota admissions run on a completely different, state-run calendar. For the 2026-27 academic year, the Maharashtra government opened online RTE applications on February 17, 2026 under revised rules. Parents can select up to 10 private unaided schools, but every selected school must fall within a one-kilometre radius of the registered home address, and all supporting documents must now be uploaded at the time of application rather than submitted later. If your child qualifies under the income/eligibility criteria for the 25% reserved-seat quota, this is a separate, mandatory-document, radius-restricted process — not an alternative route into any school in the city.

In our work with Mumbai families at findmyguru, we typically see parents discover the private-school deadline has already passed only after they've started looking at the RTE calendar, because the two are easy to mentally merge into one "admission season." Track them separately.

The Top 10 Schools

How to Actually Narrow This List Down

All ten schools above are strong; the right one depends on three things you can decide before you ever visit a campus.

Board fit first. If relocation within India is likely,Online CBSE Tutors Near Me CBSE gives curriculum continuity. If your child is strong in English/humanities and you're settled in Mumbai long-term, ICSE remains a deep foundation. If the eventual goal is undergraduate study abroad, IB or IGCSE typically makes that application process smoother — our guide on Which is Better CBSE or ICSE? goes deeper into this trade-off if you're still deciding between the two.

Commute distance, honestly assessed. A daily 90-minute one-way commute is not sustainable for a five- or six-year-old, and Mumbai traffic doesn't forgive optimistic estimates. A 30–45 minute radius from home is a more realistic ceiling.

Total cost, not headline fee. Development fees, transport, uniforms, device requirements, and activity fees can add substantially to the number quoted on a school's website — ask for the full annual figure in writing before you commit, not just the tuition line.

Once the board and shortlist are set, many families layer in additional academic support — whether that's IB-specific coaching for the Diploma years or CBSE-focused home tutoring for board-exam preparation — rather than relying on the school alone for exam-specific prep.
